[2J15] Study on debris cooling and development of experiments on coolability of particle debris
(2)Development status of analysis code for particle debris coolability
Keywords:Particle debris, Two phase flow regime, Dryout, DPCOOL
The particle-layer-pool two-phase flow analysis code DPCOOL was verified by comparison with the Lipinski 0-D theory, and validated by comparison with the measured dryout data in the heating particle layer such as the IKE-DEBRIS test and VTT-COOLOCE13 test.
Control rod guide tubes and cooling pipes are considered to contribute to the improvement of cooling performance in the debris bed. The heat transfer due to contact between the outer wall surface of the cooling pipe and the particle layer is affected not only by the contact area but also by the two-phase flow regime in the small particle size particle layer.
From this point of view, we will summarize the expectations and measurement items for the findings obtained in the particle debris cooling experiment.
